Incertain embodiments, the face mask 302 is permanently glued to the head304 after an adhesive is applied to the interior side 316 of the facemask 302.

An artificial human body or a body part may have similar structure ofthe exemplary head portion 300. That is, the artificial human body orbody part may have a skin similar to the face mask 302 resemblingoutward appearance of the human body or body part, a shell similar tothe shell 310 resembling the shape of the human body or body part. Theskin is attached to the shell to give the artificial human body or bodypart the appearance of the human body or body part.

FIGS. 9A and 9B illustrates an exemplary process of fabricating anexemplary body 200 consistent with the disclosed embodiments. As shownin FIG. 9A, at the beginning, a first mold 400 with the shape of thebody 200 is filled with a hot melted first material, such as a TPE/TPR,for making the doll. The first mold 400 may be filled up to a certainlevel. In certain embodiments, the first mold 400 is filled to asubstantially full level. The first mold 400 may be made of anyappropriate materials, such as epoxy resin, fiberglass, metal, plaster,and silicone.

In certain embodiments, the first material is a TPE/TPR. The TPE/TPR ismelted by heating the TPE resin to an elevated temperature. For TPEmaterials used in making sex toys, a temperature ranged from 120 to 170degrees Celsius is usually sufficient to melt the TPE resin. The melttemperatures may vary with polymer type and grade, and may be determinedempirically.

The melted first material is allowed to settle in the first mold 400 fora pre-determined period of time, such as about two to five minutes.While the melted first material starts to solidify during the settling,a certain amount of first material is removed from the first mold 400 toleave a layer of the first material attached to the wall of the firstmold 400 to form the skin 202. In certain embodiments, the melted firstmaterial may be poured out of the first mold 400. Because the meltedfirst material may be viscous and the melted first material close to thewall of the first mold 400 may tend to solidify first, a layer of thefirst material attached to the wall of the first mold 400 may not beremoved by pouring and may be left to form the skin 202.

The thickness of the skin 202 may be ranged from ⅛ inch to ½ inch, suchas about ¼ inch. The amount of the first material remaining in the firstmold 400 and the thickness of the skin 202 may be controlled bycontrolling the pre-determined settling time and other factors. Suchfactors may be determined empirically. During the process of making thedoll, the pre-determined settling time may be adjusted. In certainembodiments, a settling time of about two to five minutes allows theformation of skin with the thickness of about ¼ inch when the meltedfirst material is melted TPE/TPR.

After the skin 202 cools down and solidifies, an adhesive is applied tothe interior side 208 of the skin 202 while the skin 202 is still in thefirst mold 400. In certain embodiments where the first material is aTPE, the adhesive is the same TPE resin of the first material for makingthe doll dissolved in a strong solvent, such as Toluene or Xylene. Asshown in FIG. 9B, after the application of the adhesive, the skin 202 iscovered with a fabric 402. The fabric 402 can be any material such ascotton, polyester or wool, or any similar fabric which generally hasrough wooly texture on both sides. Such a material may help the bondingbetween the skin 202 and the filler 212.

After the skin 202 is fully covered in the fabric 402 and the fabric 402is dry, a lid 404 is placed on the top of the first mold 400 and thespace enclosed by the first mold 400 and the lid 404 is filled with thefiller 212 such as a flexible Urethane foam. The softness, hardnessand/or flexibility of filler 212 may also vary in different parts of thebody 200. After the filler 212 is fully solidified, the lid 404 isremoved and a melted first material is placed on top to seal the exposedfiller 212. After the skin 202 over the filler 212 is formed, the body200 is removed from the first mold 400. Alternatively, the melted firstmaterial may be pre-cast into the lid 404 to form a part of the skin202. The lid 404 with part of the skin 202 may be placed on the top ofthe first mold 400. The chamber 210 enclosed by the skin 202 on thefirst mold 400 and the skin 202 on the lid 404 is filled with the filler212. The body 200 may be further processed. For example, the body 200may be cleaned, trimmed, ironed, powdered, and hand painted in someareas.

In certain embodiments, the filler 212 is a Urethane foam. The Urethanefoam may be formed by mixing a Part A compound and a Part B compound,which are liquid under room temperature. The Part A compound may includea polymeric isocyanate and the Part B compound may include a polyol. Thepolyol is a higher molecular weight material manufactured from aninitiator and monomeric building blocks. They may be classified aspolyether polyols, which are made by the reaction of epoxides (oxiranes)with an active hydrogen containing starter compounds, or polyesterpolyols, which are made by the polycondensation of multifunctionalcarboxylic acids and hydroxyl compounds. In certain embodiments, thepolyol is a polyether polyol. The softness of the Urethane foam may beadjusted by choosing different type of polyol in the Part B compound.Softer Urethane foam may result when a linear difunctional polyetherpolyol is used. More rigid Urethane may result if a multifunctionalpolyol is used.

Other compounds, such as surfactant and/or catalyst, may also beincluded in the Part A or the Part B. The ratio between the Part Acompound and the Part B compound may be pre-determined. In certainembodiments, the ratio between the Part A compound and the Part Bcompound is about 30:70 (weight/weight). The ratio may be adjustedempirically.

The mixture of the Part A compound and the Part B compound, whichremains fluid for a certain period of time, is filled in the chamber 210formed by the skin 202 or the space between the skin 202 and the lid404. The mixture is then allowed to settle in the chamber 210 or theenclosed space. The polymeric isocyanate and the polyol in the mixturemay react to expand and solidify into a dry light-weighted foam formwith open cells. The time period required for the Urethane foam tosolidify may vary depending on the conditions such as room temperatureand may be adjusted empirically. The time period may be ranged from 15minutes to 24 hours. In certain embodiments, the Urethane foam isallowed 24 hours to solidify and dry completely.

FIG. 10 illustrates an exemplary process of fabricating the head portion300 consistent with the disclosed embodiments. As shown in FIG. 10, atthe beginning, a second mold 500 with the contour of a human face isfilled with a hot melted third material. The second mold 500 may be madeof any appropriate materials, such as epoxy resin, fiberglass, metal,plaster, and silicone. The melted third material is allowed to settle inthe second mold 500 and solidify to form the face mask 302. After theformation, the face mask 302 is removed from the second mold 500. Achamber 318 may be formed by the face mask 302. The chamber 318 may befilled after the face mask 302 is attached to the head 304 to form thehead portion 300.

The head portion 300 may be further processed. For example, the headportion 300 may be cleaned, trimmed, ironed, powdered, and hand paintedin some areas. The hair 350 may also be attached to the head portion300.

FIG. 11 illustrates an exemplary process of making the doll 100consistent with the disclosed embodiments. The head portion 300 and thebody 200 may be fabricated separately and assembled together to form thedoll 100.

A doll according to the present disclosure offers several advantages.The surface of the doll may have the feeling of human skin. A user mayfeel more comfortable with the doll. Further, a user may interact withthe doll as the user might do with a human. For example, the user maytouch or squeeze certain parts of the doll, such as the breast orbottom, as the user might do to a human. The doll according to thepresent disclosure is also generally light-weighted because only a thinlayer of the skin is made of a material, such as TPE/TPR and the chamberis either hollow or filled with light-weighted material, such asUrethane foam. For example, a doll with the size of an average adulthuman may be about 30 pounds.
